A human pituitary adenoma responsible for a case of Nelson's syndrome was maintained in organ culture and the incubation medium was examined with four different RIAs; human corticotropin (ACTH), beta-MSH, lipotropin (LPH), and beta-endorphin (beta-End). All four immunoreactivites (IRs) were present in the medium obtained after 24 h of incubation. Gel exclusion chromatography under denaturing conditions (6 m guanidine HCl) revealed several immunoreactive components. Two components having both human beta-MSH (beta-hMSH) and human LPH (hLPH) IR coeluted with beta-hLPH and gamma-hLPH; a component with beta-hMSH IR but no hLPH IR coeluted with [125I]beta-hMSH; a component with human ACTH (hACTH) IR eluted at the position of hACTH. Sephadex G-50 gel exclusion chromatography revealed that approximately 80% and 20% of human beta-End (beta-hEnd) IR were accounted for by components coeluting with beta-hLPH and beta-hEnd, respectively. These data demonstrate the presence in this incubation medium of materials similar to if not identical with beta-hLPH, gamma-hLPH, hACTH, beta-hMSH, and beta-hEnd; they suggest that all of these peptides may be secreted in the circulation of patients with Nelson's syndrome.
